Cummins Natural Gas Piston Kit, New (4089348)

Is your Cummins on the fritz? We can help! New cylinder head parts will prevent the risk of damage and overheating to your engine.

We all know in order to get a million miles out of your diesel engine you need to keep it cool, well-lubricated and perform regular maintenance. Let one of those slip and your rig is going to wind up in the shop with you stuck waiting for the repair. We know additional cylinder head parts for your Cummins – like a 4089348 Piston Kit, head valves or other parts of a cylinder block – can cost an arm and a leg. That’s where 4BTdiesel steps in; we offer premium aftermarket parts for the cylinder head assembly at a much lower price than the OE.

Don’t settle for subpar parts in your diesel engine. Our products are crafted with state-of-the-art tooling and machining to ensure supreme quality. Plus, they’ve been pressure- and vacuum-tested for quality assurance.  Take your Cummins back to its glory days!
